FIELD: transport.
SUBSTANCE: invention relates to electrified AC railways and aims at increasing railroad capacity. Traction circuit consists of contact system and track circuit that make electric conductors and are spaced apart. Extra wire is suspended from isolators at contact system mast on field side at the level of said system and connected parallel with track circuit by earthing extra wire to midpoints of track circuit impedance bond with secondary winding.
EFFECT: reduced inductive reactance of traction circuit, stronger rail shielding effect, lower intensity of electromagnetic field generated by contact system and decreased contact system electromagnetic field effects for near communication lines.
